BitMEX Testnet

Hi, I can connect to BitMEX using production API credentials, but I cannot connect to https://testnet.bitmex.com. Connection using testnet API credentials fails. StockSharp.Bitmex.dll version 4.4.15.0.

I suspect that I’ve to change the endpoint somehow? I didn’t find any documentation in https://github.com/Stock...les/Bitmex/SampleBitmex and https://doc.stocksharp.c...1-8ced-f7e9468f86b5.htm

The connection log is attached.

Thanks
